The basic intention of study is to survive in this competetive world. Now it depends how you want to survive and at which level you want to take your life into.
Whatever, there are lot of streams and field, choose such which you like, which you are in intrested. There is NO field or stream that doesnt have scope. Theres scope in each and every study. So you better choose which you like, what you like to study, be it music, dancing, arts etc.
Stand out of crowd. Dont be herd of sheeps.
What I find in our society is, like " Tom is goin for medical so should I, Dick is joining Eng. that sounds so cool, even I should join, Harry is going for BBS, wow". Moreover, In our conservative society parents have specally problem with their wards choice of study, they wants them to select only selected field of their choice and this behaviour shrinks the freedom and creative mind of people like you.
Whatever always remember, in life do such work, so that you dont feel like working.
Else your life will be hectic, you will start to take your work as burden, tensions worries. Though you'll earn money, but thats not the life you've dreamt of or imagined of.
You need to be far sighted.
So take your time, before choosing your stream. Do research on net, or better get education counselling. That will help you.
All the best.
Thanks.
